Automatic Ultrasonic Ware Cleaner Launched: Dual-CPU, High-Pressure Spray & Ultrasonic Cavitation, Solves Lab Glassware

Multi-functional fully automatic ultrasonic vessel cleaning machine: Dual-CPU control + high-pressure spraying + ultrasonic synergy, with detergent residue ≤0.1 μg/cm²

The cleaning degree meets analytical chemistry standards, effectively addressing the issue of cross-contamination associated with manual cleaning.

In laboratory analysis, the cleanliness of glassware directly impacts the accuracy of test results. For trace analysis (e.g., at the ppb level), even minimal residues of detergent or particulate matter can render test results completely invalid. Traditional manual cleaning is not only inefficient, leaves high residue levels, and lacks repeatability; moreover, significant variations in cleaning techniques among different personnel lead to inconsistent cleanliness standards. Additionally, there are occupational risks such as glassware damage or cuts, and chemical exposure from strong acids, bases, or detergents.

Our newly launched multifunctional fully automatic ultrasonic vessel cleaner strictly complies with GB/T 30435-2013 "Laboratory Glass Vessel Cleaners", JJF 1524-2015 "Calibration Specifications for Laboratory Glass Vessel Cleaners", and ISO 17025 laboratory quality management requirements. It integrates multiple technologies including high-temperature softening, high-pressure stripping, saponification, oil emulsification, pH control, chelation-based water softening, polymer-assisted cleaning, high-temperature drying, and UV disinfection. Equipped with dual CPUs for mutual monitoring, 360° dual rotating spray arms, ultrasonic-assisted cleaning, and a positive-pressure air drying system, it enables fully automated, standardized cleaning and disinfection of laboratory vessels, meeting stringent demands such as those in oil analysis applications.

I. Product Overview: Multiple cleaning modes suitable for varying levels of contamination

This instrument features a 304 stainless steel housing, a mobile design, a large cleaning chamber capacity, and replaceable baskets suitable for various container sizes. Its operation interface includes a touch-sensitive color LCD screen with Chinese menus, along with automatic door operation and safety locking functions. It employs a dual-CPU redundant control architecture: the primary CPU ensures precise control of the cleaning process, while the secondary CPU handles safety monitoring and fault diagnosis; real-time cross-verification between both CPUs guarantees stable and reliable operation. Key operating modes include:

• Heavy oil contamination mode: Suitable for heavy oil-contaminated containers such as oil sample bottles, beakers, and conical flasks in petrochemical laboratories.
• Mild contamination mode: Suitable for precision vessels with mild contamination, such as volumetric flasks, pipettes, and cuvettes.
• Special mode for trace analysis: adds three steps of rinsing with pure water to ensure complete removal of any residues, meeting ppb-level detection requirements.
• Enhanced disinfection mode: Extended ultraviolet disinfection duration, suitable for microbiological laboratory vessels.
• Custom Mode: Users can freely set parameters such as wash time, frequency, temperature, hot air temperature, and drying time, which are saved permanently
• Manual Mode: Used for maintenance, repair, and equipment debugging

The system integrates a 1200 W ultrasonic unit with a high-pressure circulation spray pressure of 0.45 MPa and a flow rate of 200 L/min, combined with dual rotating spray arms that rotate 360° vertically to ensure comprehensive cleaning without dead zones.

II. Overcoming Key Challenges: From Manual Cleaning to Fully Automated Standardization

Laboratoryware cleaning has long faced three major technical challenges, which this instrument addresses through multiple innovative design solutions:

• The residues on the inner walls of the container fail to meet the required standards.

  • Key challenge: After manual cleaning, residual detergent or particulate matter often remains on the inner surfaces of containers, compromising trace detection methods such as chromatographic analysis, with cleaning results varying significantly between different personnel by several orders of magnitude.
  • Instrumental Strategy: Integrating precise pH control (final rinse water pH 6.5–7.5) with multi-step purified water rinsing technology to achieve detergent residue levels ≤0.1 μg/cm² and particulate residue ≥0.3 μm ≤1 per 100 cm²; a 1200 W ultrasonic system generates cavitation effects for effective removal of stubborn stains; high-pressure spraying ensures thorough rinsing with 360° coverage without dead zones.

• The cleaning process consumes high energy and has a long duration.

  1. Key limitations: Traditional cleaning machines exhibit significant heat loss, low drying efficiency, and excessively long single cleaning cycles, which adversely affect laboratory operational efficiency.
  2. Instrumental Design Solution: Utilizes the same insulation technology as the GC column box and a high-performance thermal insulation layer made of heat-resistant inorganic fibers, ensuring that the external temperature of the housing remains ≤40°C and the top cover temperature remains ≤50°C, thereby reducing heat loss by 60%. The positive-pressure air drying system operates within a temperature range of room temperature to 105°C with an accuracy of ±5°C, achieving rapid and uniform drying. The average annual operating cycle is approximately 90 minutes.

• Issues related to residual substances in pipelines and cross-contamination

  1. Key challenges: Conventional cleaning machines exhibit large clogged pipelines and significant wastewater retention; inaccurate detergent dosing or cross-contamination in pipelines severely compromise trace analysis results.
  2. Instrumental solutions: A multi-channel microcomputer-based automatic valve control system minimizes wastewater residue in the pipeline dead volume; detergent dispensing employs a fully isolated magnetic pump to prevent cross-contamination between different detergents; high-sensitivity temperature sensors monitor cleaning and drying temperatures in real time; the inner walls of the cleaning chamber are constructed from 316L stainless steel, featuring a smooth surface without dead zones and minimal residue accumulation.

• Disinfection effectiveness cannot be guaranteed

  1. Key challenges: Manual cleaning cannot achieve standardized disinfection, while the disinfection function of conventional cleaning machines is virtually ineffective.
  2. Instrumental specifications: Equipped with a built-in 254 nm ultraviolet disinfection lamp (power: 30 W), which is activated simultaneously during the drying phase, achieving a sterilization rate ≥99.9% and effectively eliminating common pathogenic bacteria such as Escherichia coli and Staphylococcus aureus.

III. Common Operational Errors and Avoidance Strategies (Operational Risk Comparison Table)

Based on extensive field feedback, the following incorrect operations can easily lead to poor cleaning performance or equipment failure. This instrument uses human-machine interaction prompts and physical design to help users avoid these issues effectively:

Additionally, during the automatic cleaning process, the programs for water supply, rinsing, and soft-water rinsing stages do not respond to any buttons to prevent accidental operation; the cabin door is automatically locked during cleaning to ensure operator safety; the system features four-tiered safety protections: water shortage protection, overtemperature protection, overload protection, and leakage current protection.
